18 Claims.

My invention relates to fabricated dynamoelectric machines.

A11 object of my invention is to provide a dynamo-electric machine construction in which '5 laminations are secured in assembled relation to a rigid portion of the machine, such as a base or supporting member, by plates interspersed` or interleaved in the laminations and attached to the supporting member. Another object of my invention is to provide a simple fabricated dynamo-electric machine construction which is particularly adapted for mounting on a shaft, such as an axle of a railway car or other vehicle.

Further objects and advantages of my invention will become apparent as the following description proceeds, and the particular features of novelty which characterize my invention will be pointed out in the claims annexed to and forming a part of this specification.

For a better understanding of my invention, reference may be had to the accompanying drawings in which Fig. 1 is a perspective view of an aide-mounted, direct-current motorv embodying Y my invention; Fig. 2 is a vertical sectional view 30 machine shown in Fig. 1; Fig. 5 isa sectional view on line 5 5 of Fig. 2; Fig. 6 is a sectional view on line 6 6 of Fig. 2 showing an end plate;

Fig. 7 is a sectional view on line 7 7 of Fig. 2

showing the manner of supporting the pole shoes and windings; Fig. 8 is a sectional view on line 8 8 of Fig. 2 showing one of the interspersed plates; Fig. 9 is a fragmentary sectional view on line 9 9 of Fig. 2 showing another interspersed plate; Fig. 10 is a sectional view of the machine adjacent one of the safety lugs welded to a reinforcing plate; Fig. 11 is a section on line 11 11 of Fig. 2; and Fig. l2 is a sectional View on line 12 12v of Fig. 2 showing the end plate at the commutator end.

I have shownmy invention as embodied in a fabricated stationary member or magnet frame of an axle-mounted direct-current motor. This stationary member includes a channel-shaped supporting member and bearing housing 1 extending substantially the entire length of the stationary member. The supporting member carries a bearing 2 at either end for mounting the motor on an axle or shaft, such as the axle of a vehicle.

In constructing this stationary member I prefer Til/9.116@ t0 the flange 37a. Safety lugs 40 are also to clamp an annulus of laminations 3 in any convenient manner between end plates 4 and 5, and provide annular plates 6 and 7 interspersed or interleaved in the laminations. These plates are then welded at their edges tothe supporting member and secured together to provide a rigid construction by reinforcing plates or tie bars 1'9 which are arranged in notches at 18 in the laminations 3 and the plates and which are attached n by welds along their edges at 20 to the surface of a' the laminations and the plates. The clamping pressure is then released and the laminations are firmly secured in assembled relation bet-Ween the plates and secured to the supporting member. The laminations have .their edges presented toward the supporting member and these edges are notched at 7a. to conform to the supporting member, as shown in Fig. 7, so that the supporting member forms part of the magnetic circuit of the e motor. The plates 4, 5, 6, and 7 conform to the 7b shape of the laminations, except that they have projecting portions 8, 9, 10, and 11 extending from one side of the laminations which conform to the channel-shaped supporting member to which they are attached by Welds at 12, 13, 14, s@ and 15. The interspersed plates V6 and 7 also have portions 16 and 17 extending from the side of the stationary member opposite the supporting member 1, which support the motor.

A bearing supporting. plate 21 at the pinion 85 end of the motor is welded to the supporting member as shown at 21a in Figs. l, 3, and 4, and is further supported by transverse members 22, 23, 24, and a reinforcing plate 25 Welded at 26, 27, 28, and 29 respectively, to the end plate 5 90 and the bearing supporting plate. A baffle plate 29a is similarly supported.. A bearing supporting plate 30 at the commutator end is welded at 30a to the supporting member 1 and is also secured by transverse member 31 welded to the plate 30 and 95 the end plate 4. The bearing supporting plate 21 carries Welded lugs 33 to which an end shield 34 is bolted. The plate 30 carries a concave disk 35 and a ring 35a, welded thereto which supports a bearing housing 36.

The reinforcing plate 25 is cut and bent at 37 to form a flange 37a which ts beneath the ends of the portions 16 and 17. The plate 25 is fitted about the portions 16 and 17 of the interspersed plates and welded thereto and to the plates 4, 5, and 21. Parts 16 and 17 are reinforced by a member 38 welded to the projecting portions 16 and 17 and to the bent portion orv flange 37a of the reinforcing plate 25. A foot` 39 is welded to the plate 25, as shown in Fig. 10, to support the motor if the main support is broken.

The pole shoes 4l of the main exciting poles are supported by bolts 42 passing through the 5 tie bars 19, the heads of these bolts being countersunk in the bars and the bearing housing l. The bolts 42 cooperate with a key 43 passing through a slot in theppole (shoev411 toA clamppthe pole vvshoe ine place. 'fThe pole 'shoe is-so shaped that an end 44 bears against the commutating field winding 45 and holds it in position.

While I have shown my invention as applied to an axle-mounted direct-current.motor,-. it isV apparent that my invention is generally applicable to structures in which laminations are to be secured directly to a base-or other'supporting member. tion to be limited to the particular. construction set forth, and intend in the appended claims to cover all modifications which do not depart from the spiritand scope of my invention.
